PURPOSE: A tumble type VCM(Variable Cylinder Management) valve structure is provided to manufacture a valve body with a simplified structure, to assemble a valve shaft and a valve to the valve body, and to obtain the valve which is durable against a back pressure. CONSTITUTION: A tumble type VCM valve structure comprises a valve body(100), a valve shaft(200), and a valve(300). The valve body is formed in one side of an intake manifold(1) and includes an air suction passage which connects inside the intake manifold. The valve shaft penetrates to join to the valve body to be rotated inside the valve body. The valve is fixed to the valve shaft to be integrated, thereby opening the air suction passage while rotating with the rotation of the valve shaft. |
